India, May 14 -- EU rules to boost sustainable aviation fuel may unintentionally raise costs and energy use, a study warns.

The regulations favour renewable fuels of non-biological origin from combustion-based pathways over more efficient gasification routes.

This could lead to higher costs, greater electricity use and pressure on scarce biomass.

European Union (EU) rules designed to accelerate the shift to sustainable aviation fuel (SAF) could unintentionally make fossil-free aviation fuels more expensive and energy intensive, according to new research from Chalmers University of Technology.

The study found that current EU regulations favour production pathways that consume more electricity and resources, even when more efficient alt...
